Let's divide 21940923 by 858
Our goal is to divide 21940923 by 858.

Advancing to step 1:
If we divide 2 by 858, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 858

Step 2:
When dividing 21 by 858, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 858

Let's proceed to step 3:
The number 858 fits into 219 0 times, leaving a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Fetch the next digit (4) from the dividend, attach it to 219 and continue: 2194 / 858

Step 4:
When dividing 2194 by 858, we get 2 with a remainder of 478.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1716 from 2194 and we're left with 478.
Grab the next digit (0) from the dividend, add it to 478, then carry on: 4780 / 858

Moving on to step 5:
4780 divided by 858 is 5 with a remainder of 490.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 4290 from 4780 to get 490.
Include the next digit (9) from the dividend after 490, then repeat: 4909 / 858

Going ahead to step 6:
858 can be fit into 4909 5 times, resulting in a remainder of 619.
Record the quotient 5 as the next digit in the result. 
Result so far: 255.0
If we take 4290 away from 4909, we end up with 619.
Include the next digit (2) from the dividend after 619, then repeat: 6192 / 858

On to step 7:
858 can be fit into 6192 7 times, resulting in a remainder of 186.
Record the quotient 7 as the next digit in the result. 
Result so far: 2557.0
The remainder is 186 after subtracting 6006 from 6192.
Fetch the next digit (3) from the dividend, attach it to 186 and continue: 1863 / 858

Step 8:
858 goes into 1863 2 times with a remainder of 147.
Use 2 as the next digit of our solution. 
Result so far: 25572.0
If we subtract 1716 from 1863, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 9:
1470 divided by 858 is 1 with a remainder of 612.
Write down 1 as next digit of the result. 
Result so far: 25572.1
Subtract 858 from 1470 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 10:
If we divide 6120 by 858, we get 7 and a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 25572.17
If we take 6006 away from 6120, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 11:
1140 divided by 858 is 1 with a remainder of 282.
The number 1 becomes the next digit in our result. 
Result so far: 25572.171
If we subtract 858 from 1140, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 12:
2820 divided by 858 is 3 with a remainder of 246.
Write down 3 as next digit of the result. 
Result so far: 25572.1713
Subtract 2574 from 2820 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 13:
858 can be fit into 2460 2 times, resulting in a remainder of 744.
Use 2 as the next digit of our solution. 
Result so far: 25572.17132
If we take 1716 away from 2460, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 14:
When dividing 7440 by 858, we get 8 with a remainder of 576.
Use 8 as the next digit of our solution. 
Result so far: 25572.171328
If we subtract 6864 from 7440, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 15:
5760 divided by 858 is 6 with a remainder of 612.
Put 6 as the next digit of the answer. 
Result so far: 25572.1713286
If we subtract 5148 from 5760, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 16:
If we divide 6120 by 858, we get 7 and a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 25572.17132867
The remainder is 114 after subtracting 6006 from 6120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The quotient of the division is 25572.17132867, and the remainder is 1.14e-07.
